Sea fog protection blanket

The utility model relates to a sea fog protection blanket. The sea fog protection blanket is sequentially provided with a first non-woven fabric layer, an aqueous salt buffering layer, an ion adsorption layer, an activation factor slow release layer and a second non-woven fabric layer from top to bottom in the vertical direction. The aqueous salt buffering layer is of a structure formed by arranging sepiolite fabric and vermiculite in an alternating mode. The ion adsorption layer is of a saturated zeolite layer structure. The activation factor slow release layer is of a mushroom residue mixing layer structure. The sea fog protection blanket can effectively prevent salt fog from causing salt damage to plants and prevent the phenomenon that salt on the surfaces of the plants enter the root system layers of the plants and causes salt damage to the plants in the cleaning process or raining process.
